There are nine variations on the three basic problems involving percentages.
Multiply by 100 and add a percentage sign. Remember: How to convert a decimal to a percentage Remove the percentage sign and divide by 100. Remember: How to convert a percentage to a decimal Double check your answer with the original question: 25 is 20% of what number? 25/0.20 =. Substitute 0.20 for 20% in the equation: 25/0.20 = X. Convert the percentage to a decimal by dividing by 100. Y is 25, P% is 20, so the equation is 25/20% = X. Convert the problem to an equation using the percentage formula: Y/P% = X. Double check your answer with the original question: What percent of 60 is 12? 12/60 = 0.20, and multiplying by 100 to get percentage, 0.20 * 100 =ģ. You need to multiply the result by 100 to get the percentage. Important! The result will always be in decimal form, not percentage form. X is 60, Y is 12, so the equation is 12/60 = P%. Convert the problem to an equation using the percentage formula: Y/X = P%. Double check your answer with the original question: What is 10% of 150? Multiply 0.10 * 150 =Ģ. Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10. P is 10%, X is 150, so the equation is 10% * 150 = Y. Convert the problem to an equation using the percentage formula: P% * X = Y. Read on to learn more about how to figure percentages. X and Y are numbers and P is the percentage: Let's explore the three basic percentage problems. The formulas below are all mathematical variations of this formula. You can think of the most basic as X/Y = P x 100. 
There are many formulas for percentage problems. Add or subtract a percentage from a number or solve the equations.
Use percent formulas to figure out percentages and unknowns in equations. Find a percentage or work out the percentage given numbers and percent values.
